This document discusses water scarcity around the world. It defines water scarcity as a lack of sufficient water quantity or access to clean water. Approximately 2.8 billion people experience water scarcity for at least one month each year, and over 1 billion lack daily access to clean water. The main causes of water scarcity are increasing demand from population growth and urbanization, unsustainable agricultural practices, as well as climate change reducing water supplies. The effects of water scarcity include increased water-borne diseases, loss of biodiversity, and threats to food security. India in particular faces a severe water crisis due to these factors.

3. WHAT IS WATER SCARCITY?
• Simply put, water scarcity is either the lack
of enough water (quantity) or lack of
access to safe water (quality).

people around the world, on all continents,
at least one month out of every year and
more than 1.2 billion people lack the
access to clean drinking water.

4. World Water Scarcity
• The world’s water resources are rapidly
running dry creating a global crisis for
every living being on the planet.
• 1 billion - nearly 1/6th of the world’s
population - are already facing water
shortages on a daily basis.

5. Survey
• The United Nations' FAO states that by

countries or regions with absolute water
scarcity, and two-thirds of the world
population could be under stress
conditions

water is growing at
An alarming rate.
Water Scarcity in India

8. India's water
crisis is mainly
a man-made
problem.

9. Causes
I. Demand and Usage
 Domestic
30% of the rural population lack access to drinking water.
 Agricultural
90% of total water resources used.
 Industrial
Water is both an important input.

10. II. Supply
Surface Water
Only 48% of rainfall ends up in India’s rivers.
Only 18% can be used.
Groundwater
82% goes to irrigation and agricultural purposes.
Only 18% is divided between domestic and
industrial.

11. III. Climate Change
Climate change is exacerbating
the depleting supply of water.

12. IV. Population
India needs to keep boosting
agricultural production in order to
feed its growing population.

13. V. Pollution
The polluted water then seeps
into the groundwater and
contaminates agricultural
products
when used for irrigation.

14. Effects

15. Effects
